Hosted by RM Auctions, the caliber and sheer variety of vehicles going under the hammer are unmatched by anything we’ve ever seen in the recent past, so if you happen to be in area on the dates of May 11 and 12 head down to The Grimaldi Forum and witness all of the action unfold.

If that wasn’t enough, the number of lots being auctioned has just been expanded and now includes a 2006 Ferrari Enzo FXX Evoluzione--yes, an Evoluzione--as well as a 2006 Bugatti Veyron, a 2007 Peugeot 908 diesel Le Mans prototype and a 2011 Lamborghini Gallardo GT3 race car from the Blancpain series.

The FXX Evoluzione is about as exclusive as it gets when it comes to Ferraris, so if you’re cashed up but still aren't one of Ferrari’s preferred customers than this is a prime opportunity to change all that.

The particular model up for sale bears chassis number “145766” and is estimated to be worth more than $2 million. Only 30 of these beauties were ever built and Michael Schumacher had one in black, just like the model up for sale.

The FXX cars aren’t intended just for regular sale but are instead designed as development test-beds for new technologies that eventually filter across to Ferrari’s road cars. The cars are typically kept at the Ferrari factory’s Corse Clienti department and taken to tracks all over the world where owners can get in and drive the hell out of them without having to worry about all the logistics.

Peak output from the car’s 6.3-liter V-12 is rated at 860 horsepower, which is enough for 0-60 mph runs in 2.8 seconds and a top speed of 227 mph.

It's had only one owner who was careful enough to never damage it. In short, as offered, this stellar, one-owner Ferrari Enzo FXX Evoluzione affords its fortunate next owner the unbelievably rare opportunity to join the limited roster of FXX owners--surely an opportunity unlikely to reoccur anytime soon.

By contrast, the 2006 Bugatti Veyron also going under the hammer looks downright plebeian next to the special Enzo. This particular Bug has 5,937 miles on its clock and was the very first Veyron to land in the UK. It, too, has had only one owner and comes with an extra set of wheels.

Bids are expected to reach around $1 million, which isn’t bad considering the fine condition the car is in, and in case you are unaware, the car is capable of accelerating from 0-60 mph in just 2.5 seconds and reaching a verified top speed of 253 mph.

Finally, we must mention the 2007 Peugeot 908 Le Mans prototype. Yes, one of the 700-horsepower, diesel-powered Peugeot Le Mans racers can be yours, if you happen to have a spare $2 million or so lying around.

The particular car being offered is chassis number “two” and is currently owned by the cash-strapped Peugeot Citroen PSA group. It will be the first 908 prototype to pass into private hands and represents an extremely rare opportunity.

It is powered by a 5.5-liter V-12 turbodiesel engine, which is matched to a six-speed sequential manual paddle-shift gearbox and drives the rear wheels. It won on its race debut at Monza in 2007 in the Le Mans endurance race series and has also experiences wins at Silverstone and Spa.

The momentous auction takes place on May 11 and 12 at The Grimaldi Forum in Monaco. Admission to the event requires the purchase of an official auction catalogue for 100 euros (approximately $130), which admits two and must be presented at the entrance to be granted entry. In the meantime, head over to the RM Auctions website for a detailed write-up on each of the cars being offered for sale.
